Starting To Rivet the Left Horizontal Stabilizer Skin (10/31/09)
Posted by Ethan Jacoby in Construction, Empennage, Horizontal Stabilizer, Tools on October 31, 2009
2.5 Hours -
My new torque wrench arrived in the mail today, so the first thing I did was torque the bolts holding the HS-411PP center bearing to the rear spar. The plans recommend 20-25 inch pounds of torque for these bolts, so I set them to 25 and marked them with some “torque seal.” Ok, my “torque seal” is actually some nail polish that my girlfriend bought for me earlier in the day and I went a little overboard with it. Keep in mind, this was my first endeavor into nail polish use!

My girlfriend "torque sealed" her toes.
Next, I continued my work on the left HS by riveting the bottom of HS-707 to the skin. You can use solid rivets or blind rivets here. I couldn’t figure out a good way to buck rivets in this confined space, so I decided to just go with blind rivets. I’ll try to avoid using any blind rivets on the tops, but on the bottoms, where no one will see them, I decided the blind rivets would be a better choice than trying to buck and doing a horrible job.

I chose to blind rivet the bottom side of the HS-707 rib.
Three blind rivets were also used to connect HS-707 and HS-708 to the front spar. These were also a little tricky to place thanks to the confined quarters created by the skin.

Assembly of the left HS continued by riveting the outboard most rib, HS-706, to the front spar. Using two universal head rivets.
Finally, I started to rivet the left skin to the front spar. The small flush rivets used to attached the skin are relatively easy to set, but getting the bucking bar into place was, once again, a challenge. I spent a good thirty minutes trying to develop a plan of attack. Eventually, I started to buck rivets and set all the rivets attaching the skin to the bottom of the HS-702 front spar before calling it a day.

Bucking rivets is a slow process, but I'm happy with the results so far.
Tomorrow, my Dad is coming over to lend a hand again, and I think we will be able to finish up the HS!
Pneumatic Squeezer
Posted by Ethan Jacoby in Preparation, Tools on October 24, 2009
I had the noble goal of using only a hand-squeezer on all “squeezable” rivets during my build. However, after building the tool box practice project and setting a few 4- rivets on the empennage kit, I began contemplating the value of a pneumatic squeezers.
Don’t get me wrong, using a hand-squeezer for the entire project is completely feasible. However, 4- rivets are a pain in the ASS! I really have to bear down on them and, after setting a dozen or so, my hands become sore and my forearms tired. With more time, I’m sure setting 4- rivets with a hand squeezer will become easier (and I will develop arms like Popeye!), but I decided it was time to start researching pneumatic squeezers and buy one when I found a good deal.
New pneumatic squeezers start at around $550. However, this price generally does not include a yoke. At a minimum, I will need two yokes to get full use/value of the squeezer. A 3” and a longeron yoke would be a start, and each of these cost $130ish.
My search almost ended when I found a rebuilt squeezer at Avery Tools for $449. This squeezer included a 3” yoke and an adjustable set. However, just as I was about to place an order with Avery, I hopped onto the forums at vansairforce.net and saw a for sale posting for a used pneumatic squeezer. For $495, it included a 3” yoke, a longeron yoke, quick change yoke pins, a fixed set and an adjustable set.
One thing I have learned is that the RV community is a bunch of trustworthy people, so, site unseen, I made the deal. When I returned from a week of vacation in Arizona, the squeezer was waiting for me.
I’ve only played with the squeezer a little bit and I can already tell that it is going to drastically speed-up the process of setting rivets. I can’t wait to use it on the real deal.

At About 3:30pm, an email notification popped up on my computer. The UPS tracking system said that two boxes from Brown Tool had been delivered to my apartment.

Overall, I’m very happy with the tools. Everything was packaged nicely, all the rivet/squeeze sets and bucking bars had a protective wax coating, and both the drill and the rivet gun have very nice teasing triggers. My only complaint in the bunch is that the deburring tool is a little hokey and I will probably replace it with one from Avery. Of course, there are other tools which I already know I will have to buy in addition to the kit. A back riveting plate of some sort, an edge roller, a pop rivet dimpler, and a few more power tools just to name a few.
I have to give props to Brown Tool. I placed the order and they shipped it the next day. It arrived promptly and all items were accounted for and in great condition. I’m finding that businesses dealing in experimental aviaition are generally a pleasure to deal with. Brown Tool is no exception to this rule.
Tool Kit Ordered (8/31/09)
Posted by Ethan Jacoby in Preparation, Tools on August 31, 2009
I finally pulled the trigger and ordered a tool kit. After weeks of comparing the various kits offered, Brown Tool seemed to have the best deal. The kit I’ve ordered is their, “Deluxe RV Aircraft Tool Kit – 642 Pieces! Comprehensive Kit with 3X Rivet Gun.”
This kit has all of the tools listed on the Van’s required tool list and many of the tools they list under optional. Because I have never heard anything bad about any of the major tool vendors, my decision was based solely on cost. Brown appears to give me the most for my money. Once the tools arrive, I’ll post pictures along with any thoughts I have on quality.
Next item on the agenda, purchase order the tail kit from Van’s and start building an airplane.
Air Compressor Purchased (8/22/09)
Posted by Ethan Jacoby in Preparation, Tools on August 22, 2009
I made my first “major” aircraft building related purchase last weekend. After looking all over for a good deal on an air compressor, I finally found one I couldn’t turn down. Tractor Supply was selling a 20 Campbell Hausfeld for $299. The compressor is belt-driven, oil-lubricated, and has a steel compressor pump. Campbell Hausfeld and most other vendors are selling this model for over $400, so I grabbed it.

Unfortunately, after getting it home and running it, I found it had a pin-hole in the weld around the drain valve assembly on the bottom of the tank. So, this weekend, I took it back to Tractor Supply and exchanged it for another one. After getting home, it took about 20 minutes to assemble the compressor. I fired it up and ran through the break-in procedure (let it run for 30 minutes with the valve open so the tank never fills) before finally filling the tank. The tank filled to 130 PSI in about 5 minutes. Once the pump shut off, I carefully listened for leaks and found none!
While the tank on this compressor may be smaller than what a lot of builders are using, it should do the job and then some. With a compressor in the garage, I’m itching to pull the trigger on a tool kit and empennage order!
Tools??? (8/14/09)
Posted by Ethan Jacoby in Preparation, Tools on August 14, 2009
Deciding which airplane to build now seems like it was the easy part of this crazy plan. Deciding which tools to buy is adding an entirely new layer of confusion!
According to everyone I’ve spoken to, the recommended tools list on the Van’s website is a good place to start, but it doesn’t cover everything you will need. I’ve scanned the numerous RV builder’s forums for postings about recommended tools. It seems that everyone has there own opinion on what to buy. Should I buy new or used, a kit or piece meal, high-end or save a few bucks at Harbor Freight Aviation Supply?
Let’s start with the compressor. If you ask five RV builders about what to look for in a compressor, you will get at least ten answers. However, you can pick out some common elements. It seems everyone agrees that the compressor should have an oiled motor that, if possible, uses a belt to drive the actual compressor. While oil-free means less maintenance and often cheaper, they are LOUD LOUD LOUD! Tank size is also a common article of debate. Obviously, a bigger tank means the compressor will run less. However, 60 gallon and larger compressors often run off 230V which takes away any portability. I will primarily use the tank to run a drill, rivet gun, and cut-off tool of some sort. It may be used to run a small paint sprayer for priming as well. Keeping this in mind, it seems that a 20-30 gallon, oiled, belt driven compressor would be ideal. Right now, I’m leaning towards this one, available at Tractor Supply.
Most builders recommend that you purchase one of the RV builder’s tool kits available from several aviation tool suppliers. These kits generally contain all of the tools on the Van’s recommended list, as well as several other items which many builders feel are required in addition to Van’s list. However, a local builder who recently finished his 6A (now has 120 hours flying) thinks the kits are all overpriced and purchased all of his tools separately, both new and used. With this in mind, it becomes a decision based on both money and time/patience. For me, I would rather spend a little bit more and have everything (or almost everything) when I need it rather than start building, get stuck because i don’t have the right tool, and have to wait a week for the UPS truck to show up.
There are many aviation tool suppliers out there and several of them have RV Builder’s Kits. After doing a lot of research, the vendors at the top of my list are Brown Tool, Cleaveland, The Yard, Avery, Isham and Aircraft Spruce. I spent a lot of time comparing their offerings, trying to determine what is actually needed and what is fluff (i.e. sharpies, safety glasses, ear protection…I’ll buy these things at Wal-Mart). After all the comparisons, Brown Tool’s Deluxe RV Aircraft Tool Kit w/3x Rivet Gun seems like the most bang for the buck at $1450. However, it sounds like you can’t go wrong if you purchase from any of the suppliers I’ve mentioned.
I already know that I will have to add to the Brown Tool kit. A few additional items I already know I will need include a pop rivet dimpling tool, back rivet plate, hand seamer, drill press, band saw, and bench top grinder to name a few. There are also a few items in the kit which I already own. Most of these companies seem willing to work with you and customize the kits to suit your needs. One of the best things I’ve discovered so far in this little adventure is that people in the industry actually want to help you! As I begin to purchase tools, I’ll update these pages to reflect what I actually have.
Tool Chest Purchased (8/3/09)
Posted by Ethan Jacoby in Preparation, Tools, Workshop on August 4, 2009
I can’t buy $2000 worth of airplane makin’ tools and then just leave them scattered around. I also can’t justify the outrageous cost of some of the nicer rolling tool chests available at Sears or Lowes. Fortunately, while wandering the isles of Wal-Mart, I noticed a tool chest made by a company called ProWorks. Sure, at $114 plus tax, it’s cheap, but it seems sturdy and will get the job done. Call me crazy, but I want to buy the cheapest tools that will get the job done right (and I stress right!). There’s no reason to spend $500 on something when spending $114 gets the job done with the exact same end result. Any money saved can be put back into the airplane in the form of nicer avionics or, simply, fuel.
